Frequently Updated Cobol And DB2 Interview Questions Part – 8
What Is The Function Of The Cics Translator?
The CICS translator converts the EXEC CICS commands into call statements for a specific programming language.
What Are The Differences Between An Exec Cics Xctl And An Exec Cics Link Command?
The XCTL command transfers the control to an application program at the same logical level and it does not expect the control back, while the LINK command passes the control to an application program at the next logical level and expects the control back.
What Is Eib? How It Can Be Used?
CICS automatically provides some system-related information to each task in a form of EXEC Interface Block (EIB), which is unique to the CICS command level. We can use all the fields of EIB in our application programs right away.
What Information Can Be Obtained From The Eibrcode?
The EIBRCODE tells the application program if the last CICS command was executed successfully or not.
What Is The Effect Of Including The Transid In The Exec Cics Return Command?
The next time the end-user presses an attention key, CICS will start the transaction specified in the TRANSID option.
What Is The Function Of The Exec Cics Handle Condition Command?
To specify the paragraph or program label to which the control is to be passed if the “handle condition” occurs.
What Is The Difference Between The Into And The Set Option In The Exec Cics Receive Map Command?
The INTO option moves the information in the TIOA into the reserved specified area, while the SET option simply returns the address of the TIOA to the specified BLL cell or “address-of” a linkage section.
What Is The Function Of Dfhmdf Bms Macro?
The DFHMDF macro defines fields, literal, and characteristics of a field.
What Is The Difference Between Getting The System Time With Eibtime And Asktime Command?
The ASKTIME command is used to request the current date and time. Whereas, the EIBTIME field ha the value at the task initiation time.
What Is The Function Of The Terminal Control Table?
The TCT defines the characteristics of each terminal with which CICS can communicate.
What Is A Deadlock?
A deadlock occurs when a task is waiting for a resource held by another task which, in turn, is waiting for a resources held by the first task.
Explain The Term Multi Region Operation.
MRO is the mechanism by which different CICS address spaces with in the same CPU can communicate and share resources.
What Is Meant By Program Reentrance?
A program is considered reentrant if more than one task can execute the code without interfering with the other tasks execution.
What Is The Common Work Area?
The common work area is a storage area that can be accessed by any task in a CICS system.
